I'm new to overshadowing and I am attempting to run my cpp program with mpirun.
First and foremost, I can run the executable with no difficulty when I dispatch it without mpi as
./my_prog arg1 arg2 arg3
For mpirun, I make a troubleshoot setup with "/usr/container/mpirun" in my C/C++ application and contentions as "np - 4 my_prog arg1 arg2 arg3" (both of these without the statements). Anyway I stop with mistake as I see argc < 2 demonstrating my contentions are not being perused totally when utilizing mpirun. What is the right organization to get the contentions, name of the executable and so on when utilizing mpirun in the troubleshoot design? Likewise, when I change my program to run without contentions, I see that the program doesn't stop at primary or some other breakpoints I set in the code. Peculiarly, I can troubleshoot (and stop at breakpoints) when dispatching my_prog immediately without mpirun utilizing another investigate arrangement. Additionally I can utilize my args with no issue when not utilizing mpirun.
ps:I can run and investigate fine utilizing ddd as: mpirun - np 4 xterm - e ddd ./my_prog
Much appreciated ahead of time.
